php - Unexpected T_FUNCTION, but where?

Question

I've gotten my site to run perfectly on my local machine. However, migrating to production, I get roadblocked by "Unexpected T_FUNCTION ..." error.

I've stripped everything prior to the following code and still get the error reported for line 3. I just can't figure this out.

<?php
// Auth Check.
$authCheck = function() use ($app) {         <---- Line 3

Answer 1

You are getting :

Parse error: syntax error, unexpected T_FUNCTION in [...][...] on line 4

becasue you are using PHP version less than PHP 5.3.0 upgrade your php or try using globals

PHP 5.3.0+

$app = "Hello Wolrd";
$authCheck = function () use($app) {
    echo $app;
};
$authCheck();

Below PHP 5.3.0

$app = "Hello Wolrd";
$authCheck = function () {
    global $app;
    echo $app;
};
$authCheck();

Both would output

  Hello Wolrd
